求一篇英文文献呀,毕业设计需要,带翻译,谢谢各位了

问题解答:

在现代战场上,各种军事车辆之间、士兵之间、士兵与军事车辆之间都需要保持密切的联系,以实现统一指挥,协同作战。这是一种典型的移动自组织网络。据报道这种网络在最近的伊拉克战争中得到应用,效果不错。

移动自组织网络(Mobile Ad Hoc Network,MANET)出现之初指的是一种小型无线局域网。这种小型局域网的节点之间不需要经过基站或其他管理控制设备,就可以实现点对点的通信。当两个通信节点之间由于功率或其他原因导致无法实现链路直接连接时,网内其他节点可以帮助中继信号,以实现网络内各节点的相互通信。

无基础设施需求的MANET在2001年以前还只是一个在实验室里讨论的概念,但是4年后,自组织网络已被认为是未来移动通信技术的核心组成部分之一,甚至有不少人认为自组织网络的思想将会把所有我们能想到的网络组合在一起,从而实现世界通信网络的大统一。

为什么就在短短的两三年内 Ad Hoc会流行起来呢?主要原因有两点:一是技术进步使其具有了可实现性,各种各样的终端实现交互连接与通信是一种无法逆转的潮流。无线通信技术的发展及其与微电子技术的结合,使得无线通信设备性价比大大提高,并使其成了一种日用消费品,人们想实现的无处不在、无时不在的通信梦想驱动着人们对它的研究。

二是市场需求是其发展的巨大动力,民用市场中的移动计算需求、网格、可穿戴计算、灾难救助等需要自组织网络技术。作为移动自组织网络技术的一个主要应用领域,无线传感器网络近年来就受到了密切关注,其应用前景十分广阔。它是集信息采集、信息传输、信息处理于一体的综合智能信息系统,可用于公共安全、生态环保、应急指挥、智能交通、反恐、智能家居等诸多领域。而自组织网络技术一经提出就在军事领域得到重大应用。

移动自组织网络与传统的蜂窝技术的根本区别在于移动节点之间的通信是在没有固定基础设施(如基站或路由器)支持的条件下进行的。系统支持动态配置和动态流控,所有网络协议也都是分布式的。由于这类网络的组织和控制并不依赖于某些重要的节点,因此它们允许节点发生故障、离开网络或加入网络。其技术优势明显,应用前景十分乐观。

本期专题将聚焦移动自组织网络。主要包括以下几篇文章:

1.移动自组织网络:无需基础设施的点对点通信

2.移动自组织网络的关键技术——路由协议

3.寻找无线传感器网络与IPv6的契合点

4.传感器网络标准方案——IEEE 802.15.4/ZigBee

5.设计一个无线传感器网络节点
In the modern battlefield, between the various military vehicles, soldiers, and soldiers and military vehicles between the need to maintain close contact in order to achieve a unified command, coordinated operations. This is a typical mobile self-organizing network. According to a report of such a network in the recent war in Iraq was applied, good results. <br> <br> Mobile self-organizing networks (Mobile Ad Hoc Network, MANET) the beginning that there is a small wireless LAN. This small local area network between the node without a base station or other management control equipment, we can achieve point-to-point communications. When the two communications nodes between power or because of other reasons for the link can not be achieved directly connected, the other network nodes can help relay signals to achieve within the nodes of the network communicate with each other. <br> <br> No infrastructure needs in 2001 before MANET is only a discussion in the laboratory of the concept, but four years later, self-organizing networks have been considered to be the future mobile communication technology an integral part of the core, or even a lot of people That the idea of self-organizing networks will be all we can think of the network will link together, thus achieving the world's largest unified communications networks. <br> <br> Why in a short period of two to three years Ad Hoc will be popular? » There are two main reasons: First, it has the technological progress can be realized, a variety of interactive terminals connected with the communication is a irreversible trend. The development of wireless communication technology and microelectronics technology and the integration of wireless communications equipment greatly enhance cost-effective, and it has become a daily consumer goods, people want to achieve the ubiquitous, ever in the dream-driven communication People on it. <br> <br> Second, the market demand is great impetus to its development, in the civilian market demand for mobile computing, grid, wearable computing, disaster relief and other needs of self-organizing network technology. Since the mobile network as a key technology applications, wireless sensor networks in recent years has been paying close attention to its very broad prospects for application. It is collected information collection, information transmission, information processing in an integrated intelligent information systems, can be used for public safety, environmental protection, emergency command, intelligent transport, anti-terrorism, intelligent home, and many other areas. The self-organizing network technology on the one in the military field on significant applications. <br> <br> Mobile self-organizing networks with traditional cellular technology and the fundamental difference between the mobile communications between the nodes in the absence of fixed infrastructure (such as base stations, or routers) support under the conditions of the. Dynamic support system configuration and dynamic flow control, all network protocols are also distributed. As such the organization and control network is not dependent on some important points, so they allow node failure, leaving the network or join the network. Its technical advantages obviously, is very optimistic about the prospect. <br> <br> This issue's topic will focus mobile self-organizing networks. Mainly include the following few articles: <br> <br> 1. Mobile network: There is no need of point-to-point communications infrastructure <br> <br> 2. Mobile self-organizing networks of key technologies - Routing Protocol <br> <br> 3. Wireless sensor networks find a fit, and IPv6 <br> <br> 4. Sensor network standard programme - IEEE 802.15.4/ZigBee <br> <br> 5. The design of a wireless sensor network nodes
